Is there a complete/thorough Guide on how to jailbreak iPod touch 4G for newbies? I don't understand what tinyumbrella does. I don't understand terms like baseband and blob. I don't know what people mean when they say to backup ipodtouch with itunes after saving shsh "blob"? I don't understand what order to do the instructions in. So far, all I did was download tinyumbrella for my mac and saved shsh file for my new ipod touch 4g. Now what? And what does everything mean? ahhh. Sorry, thanks..
